Variable command depending on the website

I need to create a /hello command that varies depending on the website

Hello dear Facebook user
Hello dear Twitter user
Etc.
I would like to create it, is it possible?

Hi @Nicole_Leyva ,
You can use {site} command along with {if} for this.
Something like

Hello dear {if:{site: domain}="www.twitter.com"}Twitter {elseif: {site: domain}="www.facebook.com"}Facebook {else}other {endif}user
